Faustian (adj.)

1870, in reference to Johann Faust (c. 1485-1541), German wandering astrologer and wizard, who was reputed to have sold his soul to the Devil. Fantastic tales of his life were told as early as the late 16c., and he was the hero of dramas by Marlowe and Goethe. The Latinized form of his name, faustus, means "of favorable omen."
